DeutschTuning proudly offers CSF High Performance Radiator BMW M2 2016-2021. Stay cool under pressure. This high performance radiator from CSF is the answer to your engine cooling needs. You have enough to worry about on the track so why add overheating to that list? This radiator is built with the racetrack in mind, so you get a large all-aluminum two row core which utilizes a triple-pass configuration. Two rows of CSF's B-tubes mean you get more surface area contacting the fins and thus more heat is removed. Triple-pass means all the coolant runs through the radiator three times before returning to the motor, giving the same volume of fluid more exposure to the radiating surface and removing more heat.With CSF you get full track ready performance without the usual hassle of installing high performance parts. CSF has built this radiator with all CNC machined oem style fittings and brackets so it is as simple to install as an OEM radiator would be. Why buy another plastic end-tank OEM radiator? With CSF you get peace of mind along with extreme performance. CAD/CAM designed using Unigraphics Software. OE radial and deep drawn aluminum endtanks"B-Tube" Technology - Stronger, most efficient tube in the world. Wind tunnel tested for optimal radiator core cooling efficiency.
